REXULTI® (brexpiprazole)


  • Increased risk of death in elderly people with dementia-related psychosis. Medicines like REXULTI can raise the risk of death in elderly people who have lost touch with reality (psychosis) due to confusion and memory loss (dementia). REXULTI is not approved for the treatment of people with dementia-related psychosis.
  • Increased risk of suicidal thoughts and actions. Antidepressant medicines may increase suicidal thoughts and actions in some children, adolescents, and young adults especially within the first few months of treatment or when the dose is changed. Depression and other mental illnesses are the most important causes of suicidal thoughts and actions. Patients on antidepressants and their families or caregivers should watch for new or worsening depression symptoms, especially sudden changes in mood, behaviors, thoughts, or feelings. Report any change in these symptoms immediately to the doctor.

Do not take REXULTI if you are allergic to brexpiprazole or any of the ingredients in REXULTI.

REXULTI may cause serious side effects, including:
